Bright color coatings for electronic devices

Apparatus comprising:

• a substrate;
• and
• a coating on the substrate, the coating comprising:
• adhesion and transition layers, wherein the adhesion and transition layers comprise a Cr seed layer on the substrate and a CrSiN transition layer on the Cr seed layer, and
• an uppermost layer on the adhesion and transition layers, the uppermost layer comprising a TiCrCN film, wherein the TiCrCN film is on the CrSiN transition layer, and wherein the coating has an L* value greater than 70 in a CIELAB color space, an a* value between 0 and 5 in the CIELAB color space, and a b* value between 10 and 15 in the CIELAB color space.

An electronic device, comprising:

• a structure;
• and
• a coating on the structure, the coating comprising:
• adhesion and transition layers, wherein the adhesion and transition layers comprise a Cr layer on the structure and a CrSiN layer on the Cr layer, and
• a TiCrCN layer on the adhesion and transition layers, wherein the TiCrCN layer is an outermost layer of the coating.
